This invention relates to long hinges of the kind used in certain sheet metal structures, for example, the hinges employed for the plates oi bonnet coverings for the engine of a motor vehicle, or the hinges for attaching the covers of dickey seats to vehicles or for attaching the hinged lids of luggage containers.

Hinges of this kind are commonly applied to plates having a painted or enamelled finished surface, and such surface commonly becomes scratched or damaged after a period of use due to abrasion between contacting metal parts when one of the plates is moved or opened, and the present invention provides a construction in which scratching or damage to such enamelled or painted surface is reduced or eliminated. -The subject-matter of this present application is divided from my original patent application, serially numbered 751,973 and iiled on 3th November, 1934.

Referring tothe drawingz- A v Figure 1 is a sectional end elevation of a bonnet hinge of an automobile vehicle and constructed in accordance with this invention.

25 Figure 2 is a section through a. further modication.

Figure 3 shows in perspective one of the plates of the construction illustrated in Figure 2.

IFigure 4 is a perspective View of the other plate of the construction shown in Figure 2.

Figure 5 is a sectional elevation of a slight modification of Figure 1.

In the construction illustrated in Figure 1 the hinge is adapted for connecting bonnet plates of the engine of a motor vehicle comprising primary and secondary plates I0 and I I respectively, the latter plate being turned upon itself at the edge to be hinged forming an edge I2 of double thickness and with a downwardly bent portion I3 substantially at right angles to the plane of the main portion of the plate.

One side I4 of a channel I5 is. secured to the downwardly projecting portion I3 and to the opposite side I6 of the channel are secured angle brackets I'I each of which is secured at one limb to the side I6 whilst the other limb projects inwardly across the open top of the channel.

Each bracket I1 is formed at the free edge of the inwardly projecting arm with a loop or angle I8 for engagement with the hinge pin I9.

The primary plate adjacent the edge to be hinged is pressed to form an integral cover plate or portion 2B of inverted channel form with a substantially flat top and substantially flat sides (Ol. 1li-128.1)

inclined with respect to one another and to the top portion of the channel. v v

Along the projecting edge `of the cover plate or portion 2li is a longitudinal wing 2I to which are attached flanges 22 of hinging loops or knuckles 23 adapted for pivoting lthe primary plate upon the pin I9.

The loops or knuckles 23 are arranged at spaced intervals along the length of the pin and the loops I8 are disposed within the spaces between these loops 23. i

The knuckles 23 serve to space the cover portion 2B from the hinge pin and the plate II moves tothe open position by turning the loops or knuckles i8 around the pin I 9 whilst the plate l0 moves or hinges by turning the loops or knuckles `23 around the p-in I9.

The plate I0 can be hinged to the position shown in dotted lines in which the iianges 22 contact with the inner face of the side I6 ofthe channel and similarly the hinging movement of the plate II is stopped when the side i6 engages the underside ofthe anges 22.

A gutter or channel 24 is formed at the junction of the cover portion 2i) and the plate It to balance the groove on the opposite side between the cover portion and the double edge I2 to irnprove the appearance of the hinge.

In the modification illustrated in Figures 2 to 4, the primary plate I0 is formed integrally with the cover plate or portion 25 provided with a flat top and substantially ilat side portions and the plate I0 is retained upon the pin i9 by means of tongues or portions 26 bent to embrace the underside of the pin.

The secondary plate I I is formed with an integral channel 2l' o f part circular section, the projecting edge of which is bent outwardly at 428 to vform a ange to which is secured a iiange 29 carrying the loops or knuckles 30. i 7 The flange 29 is continuous along the length of the hinge and the loops 30 are provided at spaced positions to allow the tongues 26 to engage with the underside of the Din I9 in the spaces between these loops 30. Y

The loops 3U space the cover portion 25,1rom the pin I9 whilst the'tongues 26 prevent the cover portion rising or moving out of position in use.

In the modification illustrated in Figure 5, the construction is identical in principle with that illustrated in Figure 1 and one side 3| of a channel 32 is secured to the downwardly projecting portion I3 ofthe secondary plate IIV whilst a the primary plate by engagement with the flanges 22 as shown in dotted lines and the inclination of the side 34 is such that the primary plate I0 can be moved through an angle of about degrees from the closed position shown in full lines, to the open position shown in dotted lines.

The flanges 22 engage with the side 34 with the face fitting along the entire length of the hinge and the opening movement of the primary plate is stopped in an eiilcient manner. When the secondary plate is moved to the open position the channel 32 moves relative to the pin I9 and opening movement of the secondary plate is arrested when the side 34 of the channel engages the underside of the flanges 22.

In all the constructions described above the cover plate or portion is of inverted channel shape and the sides of the channel are supported from the hinge pin so that the cover plate is strengthened and stiifened against distortion or bending in use.

The cover plate seats upon the knuckles engaging the hinge pin and is supported along its length and along a plurality of lines which are spaced angularly around the peripheries of the loops so that distortion of the cover plate due to localized support is eliminated. V

In addition the cover plate is supported across its width without causing excessive lfrictional contact between the cover plate and the loops of the hinge plates so that the latter can be moved around the pin without considerable friction between the loops and the cover plate although the sides. of the cover plate are supported and reinforced.

The support of the cover plate along a plurality of spaced lines disposed angularly around the periphery of the hinge pin prevents the cover plate moving laterally with. respect to the hinge pin in a downward direction, and in the constructions in which the cover plate has portions engaging beneath the hinge pin, movement of the cover plate laterally in an upward direction is also prevented.

In all the constructions suiicient clearance is provided between the cover plate and portio-ns of the hinge adapted to move around the cover plate so that scratching or damage of the exposed surface of the hinge, and particularly the upper surface of the cover plate, is prevented.

If there is any frictional or rubbing contact between the cover plate and any parts of the hinge which are moved with respect to the cover plate when the hinge is in use, the painted or polished finish of the cover plate becomes damaged and the appearance of the hinge is impaired.

The invention has been described as applied to the plates of bonnet coverings for the engine of a motor vehicle, but it will be appreciated that it may also be applied to the hinges for attaching the covers of dickey seats to vehicles, or for attaching the hinged lids of luggage containers, or for any other application in which it is desired to provide a longsubstantially continuous hinge and weather protection is needed to prevent water or the like passing between the joints in the hinge.
